Congratulations! You have a very similar unit to mine, which is an EFOZ6.5 230v. I have been very happy with mine which is dead simple, overbuilt, heavy, quiet, reliable. 1000cc three-cylinder totally mechanical Yanmar diesel
with no electronics
at all, running at a lazy 1500RPM. I have four years of experience with it. I think Kohler is not quite as good as Northern Lights
, but they are built according to similar principles. The opposite of Fischer Panda
I have no idea what you mean about the battery
charger "keeping up" with the current
from the generator
. The charger will draw what it needs, provided it is available (and if not, it will blow breakers). 60 amps is quite small for 900 amp/hours of batteries, and Xantrex is the -- erm -- Fischer Panda of chargers. So if I were you, I would make a clean sweep of all the crap in your electrical system
and toss out the charger as well.
You might consider a charger/inverter with power boost, which will use inverted battery power to supplement a weak shore power
connection -- extremely handy. I have one of this -- a Victron -- which works fabulously when it works, but I'm not sure I can recommend it whole-heartedly as I've had trouble with it, like with every other item of Victron equipment
on board. You might look at Mastervolt charger/inverters which do the same thing; I don't know personally whether they are more reliable than Victron. For a charger-only which is bulletproof, look at Newmar. For a charger which is great value for the money
, and they say very reliable, look at Sterling. Stay away from the X brand!
For 900 amp/hours of batteries, you probably want about 120 to 150 amps of charger. Much more than that and you will be stressing your batteries while charging
; less than that and you will need inordinately long generator runs to charge up. 60 amps is definitely too small for such a big bank.
Good luck and let us know what you do in the end.
